We look at the division of 417459 by 43 
The aim is to understand the frequency of 43 in 417459.

Step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 43

Let's proceed to step 2:
43 goes into 41 0 times with a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 43

On to step 3:
The number 43 fits into 417 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 387 from 417 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 43

Let's proceed to step 4:
43 can be fit into 304 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 301 from 304, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 43

Moving on to step 5:
43 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 970.0
If we subtract 0 from 35, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 43

Advancing to step 6:
359 divided by 43 is 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 9708.0
The remainder is 15 after subtracting 344 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 9708.3
Subtracting 129 from 150 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 9708.34
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
When dividing 380 by 43, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 9708.348
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
When dividing 360 by 43, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9708.3488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 9708.3488 with a balance of 0.00016.
